In mid-to late-summer, the hosta foliage supports elegant stalks of bell-shaped flowers in white or shades of lavender. White flowers usually have a sweeter scent than the lavender. These sturdy plants continue to add interest into the autumn as the impressive clumps of foliage take on the golden tones of the season.
Some hosta flowers are double-flowered white such as 'Aphrodite' and 'Royal Standard'. Their trumpet-like flowers appear in late summer and have a heady gardenia-like fragrance that makes them lovely for cutting.
New cultivars of hosta plants are also being bred to produce larger and even more attractive flowers. Some newer plants may have 50–75 blooms on each flower scape. All fragrant hosta flowers are hybridized from Hosta plantaginea, which has 6-inch long, beautiful, white fragrant flowers.
